Re: [TLS] Consultation About Assignment of ExtensionTypes

[Stephen Farrell <[e-mail]>]

Hiya,

I think these are 16 bit code points?  If so, I would
barf slightly less if we could allocate 0x0bad every
time.

I do think signalling opprobrium somehow would be right
here. Not sure how best we ought do that though tbh.

Cheers,
S.
